Thats intersting, because they have this official post on their forum:
What are the reccomended hardware specifications for the game?
Operating System: Windows 98/2000/ME/XP
Processor: 2 GHz or greater
RAM: 1 GB
Video Card: DirectX 9 compatible; pixel shader and vertex shader compatible hardware with 128 MB or more of texture memory
Sound Card: DirectSound compatible audio hardware
What type of video card will I need for EQII?
You will need a card that supports DirectX 9 features, such as pixel and vertex shaders.
Does that include the Nvidia GeForce MX line of cards?
Unfortunately the GeForce 4 MX cards are not supported because they do not have pixel and vertex shaders.
